`$eq` permissions granted when not listed

[Helveg]

It seems from the code that $eq permissions are always granted on a column, which probably snuck in as a way to allow things like the $not:5 token to work:

nestjs-paginate/src/filter.ts

Lines 292 to 298 in 60d9e1e

	if (
	token.operator &&
	token.operator !== FilterOperator.EQ &&
	!allowedOperators.includes(token.operator)
	) {
	continue
	}

In order to hit that line you have to make it past:

        if (!(column in filterableColumns)) {
            continue
        }

which means this doesn't affect columns that aren't explicitly listed. But if my hunch is correct, then:

paginationConfig = {
  filterableColumns: {
    colA: [FilterOperator.LT],
    colB: []
  }
}

would give the $eq permission to both colA and more importantly for colB, which might leak unwanted filtering capacities to consumers?
